Read More2019115 The watercement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticiers or superplasticiers. Often the ratio refers to the ratio of water
